Cenforce 200 mg is a medication marketed for the treatment of erectile dysfunction (ED) in men. It contains sildenafil citrate as its active ingredient, which belongs to a group of medicines called PDE5 inhibitors. Sildenafil improves blood circulation to the penis, helping men achieve and maintain erections during sexual stimulation. Sildenafil works by inhibiting the PDE5 enzyme, which relaxes blood vessels and increases blood flow to the penis during sexual stimulation. It does not increase sexual desire or automatically produce an erection.
